Why is the volume on a humbucker louder than a single coil pickup?
This is not always true and much has to do with the design, components and construction of each pickup. Humbuckers are generally louder because of the traditional two bobbin design that senses a wider string area. We’ve made some single coil pickups just as hot as some standard humbuckers. There are many variables including the location, height, number of turns, magnet, type of pole and magnetic path that contribute to the loudness of a particular pickup. In my opinion it is far better to have a great tone than just a loud pickup. I’ve always talked about great sounding pickups and such examples are one’s out of a late 50’s Fender Duosonic guitar. When used in a Strat with floating tremolo plugged into a black face Fender Deluxe Reverb amp have one of the sweetest tones I’ve heard. They are also some of the favorites of guitarist, Eric Johnson.
